BR green sleeveless blouse size M

GUC sleeveless blouse by Banana Republic in size Medium. Green with white dotted line pattern. Sleeveless with lovely pleat detail at round neckline. Popover design with no stretch. Please note no stretch and seems like it tends on the smaller side of medium. Tag with care and fabric content has been removed. I would guess polyester. Measurements~ armpit to armpit: 18" center back to hemline: 23"
